Partial splenic torsion with spontaneous resolution in a dog

Objective. The objective of this study is to report a case of primary partial splenic torsion with spontaneous resolution observed during two ultrasonographic examinations. Materials and Methods. An 11-year-old Swiss Shepherd dog underwent a geriatric evaluation, presenting no reported clinical complaints. Laboratory and imaging examinations were conducted for further assessment. Results. Ultrasonography revealed splenomegaly and redirection of the splenic head with immediate repositioning. Doppler ultrasonography detected an interruption of splenic venous flow before repositioning. Partial splenic torsion with spontaneous resolution was suspected, and follow-up ultrasonography was recommended in thirty days. Subsequently, splenic torsion occurred after the patient became agitated. Although splenopexy was recommended, the owner disagreed. Two months later, the patient presented with acute abdominal pain and a firm mass in the left abdominal region. Ultrasonography revealed an enlarged spleen with dilation of intrasplenic veins and intraluminal hyperechoic formations. During the splenectomy, laxity of the gastro-splenic ligament was observed. Conclusions. It is concluded that ultrasonography facilitated the identification of partial splenic torsion on two occasions, despite the absence of secondary clinical signs, and assisted in diagnosing other alterations.
